Abstract A basic hypothesis of firearms identification is the uniqueness of the striations and marks left on fired bullets and cartridge cases respectively. This paper reviews the studies so far reported in the literature on this issue, applied to consecutively (or closely) manufactured components of a firearm. A correct firearms identification starting from the striae on a bullet can be performed if one takes into account a few basic rules which are independent of the specific rifling technique applied to the barrel. However, the identification starting from a cartridge case has to be performed with care, exploiting as much as possible all the marks left during the firing process.
